Valoración clínico radiológica a los 3 y 5 años de la función en prótesis fijas implantosoportadas(Sistema Branemark)

Abstract

OBJETIVE: To value the influence of the prosthetic function on the supporting bone tissues. MATERIAL AND METHOD: Fifty-one fixed prosthesis of 139 Branemark implants, placed at the Master of Implants of the Dentistry Faculty of Madrid, were studied. All parameters that value the function of the prosthesis with the degree of bone loss and quality around the implants that support them, were compared after three and five years. RESULTS: Although some prosthodontic parameters reveal to be of no importance, others, such as the prosthesis' stability or the length of the cantilever seem to have a direct influence on the state of the supporting bone. In the case of absence of stability or too large free extremes, the bone quality and quantity diminishes during the implants´function. CONCLUSIONS: It is difficult to value influence of the posthetic function on the supporting tissues of the implant, due to the small sample and the large number of variable (... type, material, ... edentulous interval, number of implants, etc) It seems clear that the stability and the length of the cantilever are two fundamental factors in the long term prediction of the treatment.
